DUST-COLLECTO R.

SPECIFICATION forming part of Letters Patent No. 370,020, dated September 13, 1887,

Original application filed June 9, 1886, Serial No. 204,684.

Divided and this application filed August 20,1887. Serial No. 247,430. (No model.)

To aZZ whom it may concern.-

Be it known that l, ORYILLE M. MORSE, a citizen of the United States, residing at J ackson,in the county ofJackson and State ofMichi- 5 gan, have invented new and useful Improvements in Dust-Collectors, of which the following is a specification.

This invention relates to a dust-collector which is provided with a conical or tapering IO separating-chamber, into which the dust-laden air is delivered from a tangential inlet-spout, whereby the air is caused to assume a whirling or gyrat-ing motion in the separating-chain.- loer. This motion of the air causes the dust to 1 be deposited against the inner surface of the tapering chamber, from which it is discharged through a small opening at the apex or small end of said chamber. Adust-collector of this kind is described in an application for patent 2o filed by me March 31, 1886, Serial No. 197,307. The object of my present invention is to provide the dust collector with an automatic cleaner, whereby the discharge of the dust from the case is facilitated and the dust is prevented 2 5 from accumulating in the dust-discharge opening.

My invention consists of the improvements, which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of a dust-collector provided with my improvements. Fig. 2is a top plan view of the same on a reduced scale. Fig. 3 is a horizontal section in line so a, Fig. 1, on 35 a reduced scale.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the dustcollector, and B the conical or tapering 4o separating-chamber supported in the frame A. represents the spout through which the dust-laden air enters the large end of the cham ber B in a tangential direction.

d represents the discharge-opening for the 5 dust, formed at the apex or small end of the separating-chamber B.

E represents the cover or head, which incloses the large end of the chamber B, and which is provided with a large central opening, 6, through which the purified air escapes from the machine.

f is a tubular guard secured to the head E in the opening 6.

The dust-laden air enters the tapering chamber B in a tangential direction and assumes a 5 whirling or gyrat-ing motion in the same, forming a vortex in which the dust particles are quickly driven to the periphery of the whirling body of air and against the inner surface of the separating-chamber, thereby freeing the inner portion of the whirling body of air from dust. The dust particles move in helical lines toward the small end of the separating-chamber B, and escape finally through the opening (1. The air, which has been freed from dust, escapes through the central opening, 6, which is protected by the depending tubular guard f.

G represents a wiper or cleaner, which extends into the dust-discharge opening (I, and which is rotated by the whirling body of air in the separating-chamber, thereby facilitating the discharge of the dust through said opening and preventing the latter from becoming clogged with dust. The cleaner G rests with its lower end upon a step-bearing, g, which is secured to the separating-chamber B, and depends below the dust-discharge opening d.

As shown in the drawings, the cleaner G may extend only through the small portion of the separating-chamber, as the large portion of the same is kept clear by the air-current when working upon ordinary dust; but when the dust is very adhesive the cleaner may eX- tend to the large end of the separating-chamber. The upper end of the cleaner may be provided with a head, h, of leather or other suitable material, to prevent noise. The cleaner is so light that it is readily rotated by the whirling body of air in the separatingchamber. go

In this application, which is a subdivision of an application filed by me June 9, 1886, Serial No. 204,684, I do not wish to claim the construction of the separatingchamber per se, or any other improvement in the dust'col- 5 lector herein described and shown, except the improvements specifically pointed out in the claims, but reserve the right to claim all other improvements in pending applications hereinbefore mentioned.

I claim as my invention- 1. The combination,with the tapering separating-chamber provided with means whereby the air is caused to rotate in the same, and

with an air-discharge opening in its large end' and a dust-discharge opening in its small end, of a rotating cleaner extending into the dustdiseharge opening, whereby the dust is prevented from accumulating in the same, substantially as set forth.

2. The combination,with the tapering separating-chamber provided with means whereby the air is caused to rotate in the same, and with an air-discharge opening in its large end v and a dust-discharge opening in its small end,

of a cleaner extending into the dust-discharge opening and arranged loosely in the separating-chamber, whereby it is caused to rotate with the whirling body of air, substantially as set forth.

3. The combination,with the tapering separating-chamber provided with a tangential inlet-spout, and with an air-discharge opening in its large end and a dust-discharge opening in its small end, of. a bearing arranged below the dust-discharge opening, and a cleaner resting in said bearing and extending upwardly through the dust-discharge opening into the separating-case, substantially as set forth.

4. The combinatiomwith the tapering separating-chamber provided with means whereby the air is caused to rotate in the same, and with an air-discharge opening in its large end and a dust-discharge opening in its small end,'

of a bearing arranged below the dust-discharge opening, and a cleaner, G, resting loosely on said bearing and provided at its upper end with a head, 72, resting against'the inner side of the separatingchamber, substantially as set forth.

Witness my hand this 11th day of August,

ORVILLE M. MORSE. Witnesses:
